EN steel grade S460N material material heat treatment

The EN steel grade S460N material, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..

Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes. Our EN steel grade S460N material customers in the world has about 4000 clients in 70 countries such as Bangladesh, Saudi Arabia, Iran, Iraq, United Arab Emirates, Qatar, Bahrain, Oman, Kuwait, Turkey, Egypt, Jordan, Philippine, Singapore, Malaysia, Indonesia, Thailand, Vietnam, South Korea, Japan, Sri Lanka, Bangladesh, Argentina, Brazil, Colombia, Guyana, United States Of America, Canada, Mexico, Jamaica, Germany, France, Italy, United Kingdom, Spain, Netherlands, Belgium.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This EN steel grade S460N material method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In EN steel grade S460N material, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
